Outdoor performance of the black globe temperature sensor on a hot and humid tropical region.

A crucial variable to evaluate thermal comfort is the mean radiant temperature (T). In this paper we evaluate the performance of the 150 mm black globe thermometer to provide reliable T values for outdoor settings in Singapore. Accurate T values are calculated by the method of integral radiation measurements.

Numerical analysis of the impact of anthropogenic emissions on the urban environment of Singapore.

Increased urbanization and anthropogenic activities in tropical cities lead to the temperature gradient between the urban and rural environments, causing the urban heat island (UHI) phenomenon. This study is a pioneering attempt that examines the changes in the temporal evolution of the surface energy budget induced by urbanization known as the Anthropogenic Influence (AI) in modifying the urban climate of a tropical city using Weather Research and Forecasting (WRF) numerical modeling system. The AI from buildings, traffic and power plants is determined in five different scenarios and the model is validated with high temporal resolution in-situ data.

Effects of Orientations, Aspect Ratios, Pavement Materials and Vegetation Elements on Thermal Stress inside Typical Urban Canyons.

The analysis of local climate conditions to test artificial urban boundaries and related climate hazards through modelling tools should become a common practice to inform public authorities about the benefits of planning alternatives. Different finishing materials and sheltering objects within urban canyons (UCs) can be tested, predicted and compared through quantitative and qualitative understanding of the relationships between the microclimatic environment and subjective thermal assessment. This process can work as support planning instrument in the early design phases as has been done in this study that aims to analyze the thermal stress within typical UCs of Bilbao (Spain) in summertime through the evaluation of Physiologically Equivalent Temperature using .
